You should connect your Ammeter in series with the battery then leave it switched off for 20min (to save the battery), then switch it on and take your measurement. That's all there is in the circuit.īTW, how long are you measuring the current drain for?ĭo you know it can take 15~20mins for all the electrics to switch off? Has anyone had this issue or possibly know what could be causing the problem? Is there some sort of work around till I can afford to have someone take a look at the circuit? Am I completely off? I have been removing the fuse at night and putting it back in in the morning just to avoid having to jump the car.Ĭlick to expand.The three fuses your going to check are what's controlled by the leak autocut devise. Unfortunately this isn't a fuse I can live without as my car will not shift without it. It would seem that the only way to get rid of parasitic draw is by removing the fuse in the engine compartment for B+3. I was able to pull all of these fuses to check and see if it narrowed it down even further except for the Autocut Device however this did nothing. I figured out that the B+3 circuit contains Module 1, PDM 1 and 2, Dr Lock and something called Leak Current Autocut Device. After finding this out I proceeded to pull the corresponding fuses in the inside fuse box by the steering wheel column. I started with the fuse box in the engine compartment and when I yanked the B+3 Fuse for the smart junction box, the amperage draw (which was bouncing between 1.5 and 12) dropped to a steady 0.2. I did this using a multimeter and by pulling fuses one by one till I found the problem circuit. The next thing that I did was to test for a parasitic draw on the battery. I ended up getting a Duralast Gold from Sears and I thought that would fix the issue but much to my dismay, it did not. After dealing with it by simply jump starting it every morning I am about at my wits end due to the cold weather so I did what anyone probably would do and replaced the battery. After I had these repairs (or about 2 months after) the car would seem to drain completely overnight. I believe the issue started after my car was in a front end accident where the complete front bumper, fog light and headlight were all replaced. I have recently been having trouble with my 2012 Elantra GLS dieing overnight (complete battery discharge) and have become very annoyed by it.
